Mostly correction of errors in the exynos5433 SoC
clocks definition, dropping read-only registers

and exposition of two clocks required for the

Currently the Exynos5433 (ARMv8 SoC) clock driver depends on ARCH_EXYNOS
so it is built also on ARMv7. This does not bring any kind of benefit.
There won't be a single kernel image for ARMv7 and ARMv8 SoCs (like
multi_v7 for ARMv7).
Instead build clock drivers only for respective SoC's architecture.

Pull ARM DT updates from Olof Johansson:
"As usual, the bulk of this release is again DT file contents.
There's a huge number of changes here, and it's challenging to give a
crisp overview of just what is in here. To start with:
New boards:
- TI-based DM3730 from LogicPD (Torpedo)
- Cosmic+ M4 (nommu) initial support (Freescale Vybrid)
- Raspberry Pi 2 DT files
- Watchdog on Meson8b
- Veyron-mickey (ASUS Chromebit) DTS
- Rockchip rk3228 SoC and eval board
- Sigma Designs Tango4
Improvements:
- Improved support for Qualcomm APQ8084, including Sony Xperia Z DT files
- Misc new devices for Rockchip rk3036 and rk3288
- Allwinner updates for misc SoCs and systems
... and a _large_ number of other changes across the field. Devices
added to SoC DTSI and board DTS files for a number of SoC vendors, new
product boards on already-supported SoCs, cleanups and refactorings of
existing DTS/DTSI files and a bunch of other changes"

It is allowed to enable/disable clocks from interrupts, so common Exynos
ARM clock management code for CPUfreq should use 'irqsave' version of
spin_lock calls to avoid potential deadlock caused by spin_lock recursion.
The same spin_lock is used by gate/mux clocks during enable/disable calls.
This deadlock, can be reproduced by enabling CPUfreq (ondemand or
userspace) and decoding video with s5p-mfc driver.

configuration data and instantiate the CPU clock type for Exynos5420.

(Specific details on what's actually here and new is pretty easy to
tell from the diffstat, so there's little point in duplicating listing
it here)"

When the DISP1 power domain is powered off, there's two clocks that need
to be temporarily reparented to OSC, and back to their original parents
when the domain is powered on again.
We expose these two clocks in the DT bindings so that the DT node of the
power domain can reference them.

As per UM, sclk_mmc2 is bit 16 of SEL_TOP1_FSYS0. Also the DIV
and the GATE clocks are at bit 16 in their respective registers.
For mmc1 and mmc0 clock MUXs are in TOP1_FSYS11 instead of TOP1_FSYS1.
And their DIV and GATE clks are in xxx_TOP1_FSYS11 instead of TOP1_FSYS1.
This patch corrects it.
This also adds xxx_FSYS11 to be saved/restore during s2r cycles.

dependencies on things being merged from other trees.
The bulk of the changes are for samsung/exynos SoCs for some changes
that needed a few minor reworks so ended up a bit late. The others
are mainly for qcom SoCs: a couple fixes and some DTS updates"

With the addition of the new Samsung specific cpu-clock type, the
arm clock can be represented as a cpu-clock type. Add the CPU clock
configuration data and instantiate the CPU clock type for Exynos4x12.

Commit d5e136a21b2028fb1f45143ea7112d5869bfc6c7 ("clk: samsung: Register
clk provider only after registering its all clocks", merged to v3.17-rc1)
modified a way that driver registers registers to core framework. This
change has not been applied to s5pv210 clocks driver, which has been
merged in parallel to that commit. This patch adds a missing call to
samsung_clk_of_add_provider(), so the driver is operational again.

Use the provider based method to get a clock's name so that we
can get rid of the clk member in struct clk_hw one day. Mostly
converted with the following coccinelle script.

struct clk_hw *E;

-__clk_get_name(E->clk)
+clk_hw_get_name(E)

We're removing struct clk from the clk provider API, so switch
this code to using the clk_hw based provider APIs.
